Model 600-SL - Safety and Relief Valve

Unlike traditional flat-disc technology, the Target Rock disc has an angled surface to create a line seating interface with the nozzle. Line seating concentrates seating forces to provide tighter sealing and highly repeatable set pressure performance. The disc is not the only innovation employed in this design. Advanced flow analysis has resulted in a proprietary pressure balance system eliminating the need for adjusting rings.

The Inverted Cone SRVs have an elegantly simple construction with few parts. Advanced flow analysis and extensive R&D testing have resulted in a proprietary pressure balance system eliminating the need for adjusting rings to generate the forces necessary to "pop" the valve, greatly simplifying maintenance and testing.
